Switch / Joystick Functionality
The Mini-PAC works identically to the I-PAC2 board. All programming functions are the same, with the same number of inputs (32). Operates in both PS/2 and USB modes. For PS/2, the optional adapter is required.

Compact PCB – only 57 x 38 mm!
Fully programmable keycode set, stored even after power-off (unlike some other interfaces that lose data).
Dual interface: Full Speed USB or keyboard. Small adapter plug available for PS/2 mode.
Cable can connect to the PC’s keyboard port (with adapter) or directly to the USB port.
Programmable with dedicated utilities (DOS, Windows, Linux, Mac).
Unlimited number of keycode configurations can be stored and loaded on-the-fly.
No separate power supply required.
No matrix → no ghost keys.
No scanning method with variable delay: each input has its own direct connection to the CPU.
Fast processing → much better response than standard keyboard controllers.
No delay between simultaneous key presses (essential for fighting games).
Two modes: standard MAME keys (default) or fully programmable.
Shift functions: hold “Start1” and press other buttons to send codes for MAME functions such as “Escape”, “Coin 1”, “Tab”, “Enter”. No extra buttons required.
Connector for a regular keyboard, allowing panel and keyboard use simultaneously.
Advanced interrupt-driven code → no CPU load when the keyboard is idle.
Supports selective key repeat in PS/2 mode (USB repeats all keys).
No special drivers required, USB uses standard Windows drivers.
Fully compatible with all Apple Macs with USB ports.
Supports the Mac “Command” key and Windows “GUI” keys.
Can be combined to increase the number of inputs.
Keycode programming integrated into many popular MAME frontends.
Self-test LED indicates wiring or other issues.
